Dogs With Lens Changes

At MedVet Columbus


MedVet Columbus is enrolling dogs with Nuclear sclerosis or cataracts in a study to evaluate the safety and efficacy of a topical ophthalmic solution in delaying the progression and/or reversal of lens changes in dogs. Patients will be randomized into one of two dose concentration groups.

Qualifications to Enroll:

  • Dogs must be diagnosed with bilateral nuclear sclerosis or cataracts (with or without diabetes) by the Primary Investigator
  • Dogs must not have KCS, glaucoma, uveitis, or lens luxation
  • Patients may not have been part of another clinical trial in the past 6 months
  • Dogs must not have any active infections or systemic organ dysfunction that would limit full participation in the study
  • Owners must be able to return for all study visits (screening, week 2, week 4, week 8, week 16)
  • Owners must be able to treat their dog with eye drops three times a day.

Client Savings:

All costs associated with the study will be covered by the study sponsor including: ocular exams by a board certified ophthalmologist, photographs, labwork, and test article. Owners that complete the full study will be eligible for a sponsor incentive (Prepaid gift card) as well as the possibility of continued use of the product and additional exams up to one year.

Dogs in Need of an Amputation



MedVet Columbus is currently enrolling patients in a clinical study to evaluate the outcomes associated with two different methods of wound closure after limb amputation. Each patient will be examined by a veterinary surgeon to determine if he/she is an appropriate candidate for amputation. If your dog is eligible, at the time of surgery he/she will be randomly assigned to have the surgical site closed with or without placement of a closed suction drain. The drain will remain in place for approximately one week. A closed suction drain requires emptying at home two to three times a day until it is removed.

All owners must be willing and able to present patients for follow-up examinations at one, two, and four weeks postoperatively. Owners will be asked to evaluate their dog’s overall pain, level of pain interference, and overall quality of life and veterinarians will assess comfort, ambulation, incisional healing and any other complications.

Qualifications to Enroll:

  • Patients will be evaluated by a member of the surgery service to confirm eligibility
  • Dogs must be greater than 26.4 pounds (12 kilograms)
  • Either forelimb or hind limb amputations
  • Reason for amputation may include cancer, trauma, peripheral nerve problems, or severe infections
  • Dogs are excluded if the patient requires an additional surgical procedure (e.g. eyelid mass removal)

Client Savings:

Clients will have three free follow-up examinations courtesy of the surgery department at 1, 2, and 4 weeks post-amputation.
